EBPECIFICATION forming part of Letter '5 Patent No. 940,535, dated April 20, 1886.

Application filed February 2, 1886. Serial No. 190,583. (No model.)

To (ZZZ whom it may concern.-

Be it known that I, EMIL ZIMMERMANN, of the city of New York, county and State of New York, have inventedanew and Improved \VorkSupport for Lathes, of which the following specification is a full, clear, and exact description.

This invention relates to a rest for supporting the work while being turned in a lathe and preventing the same from sagging. The rest or support is vertically adjustable, and is constructed with a view to permitting the free rotation of the work.

The invention consists in theelements of improvement hereinafter more fully pointed out.

In the drawings, Figure l is a sectional side view of my improved work-support for lathes. Fig. 2 is a section through the collar on linex x,l*ig. 5; Fig. 3, a side view of the collar when open. Fig. 4 is an end view of the work-support for lathes, and Fig. oanend view of the collar.

The letter a represents an upright post, screwthreaded near its upper and lower ends, and connected at its upper end to a sectional ring, D. The two sections of this ring are hinged together at one end,while their free ends are provided with outwardly-projecting lugs 0, which have screw-threaded perforations for the reception of a thumb screw, d, by means of which the sections may be lirmlylocked together. The ring 1) contains an annular collar, 6, adapted to turn within ring I), and in turn to receive the work. The collar 6 is also made in two sections, so that it may be opened or closed. Each section has two side lugs at one end and a central lug at the other end. The

side lugs of one section embrace the central log of the other section and by passinga pin through the logs the sect-ions are properly locked together. a

ff are headless screws passing through collar e and bearing with their inner ends against the work, so that the collar may be clamped to and rotate with the work. There is no tendency of the collar e to slip out of ring I), and no means for preventing lateral displacement of the collar are therefore shown in the drawings; but, if desired, the collar may be provided with a surrounding annular groove, for the reception of the end of a pin or setscrew passing through the ring. The post a is embraced by a block, 9, which has an offset, h, near its lower end, so as to set upon the side pieces or bed, i, of the lathe. At its upper end the block 9 has a screw-threaded head, j, while a winged nut, 75, that embraces the lower end of post a,hears against thelower end of the block. If the worksupport is to beelevated, the posta is screwed up and fastened in position by the winged nut 70. To lower the work support, the post is screwed down and the nut is then screwed up.

I claim as my invention- 1. The combination of post a, carrying sectional ring I), with the collar e, provided with adjusting-screws f, substantially as specified.

2. The combination of screw-threaded post a, carrying sectional ring I), having lugs c and screw-d. with the collar 0, having screws f, and with the block g. that embraces post a, substantially as specified.

3. The combination of screwthreaded post a,ring b, and collar 0, with the block g, having offset h, and perforated head j, and with the winged nut 70, substantially as specified.

EMIL ZIMMERMANN.
